BACKGROUND

Thymidylate metabolism is required for producing essential buildingblocks necessary to replicate DNA in dividing cells and has long been animportant therapeutic target for cornerstone cancer drugs. Drugstargeting this pathway such as 5-fluorouracil (5-FU) inhibit the enzymethymidylate synthase (TS) and are currently critical standard-of caretherapies. TS-targeted agents are used for the treatment of a variety ofcancers including colon, gastric, head and neck, breast, lung and bloodrelated malignancies among others. Grem, J. L., 5-Fluorouracil plusleucovorin in cancer therapy, in Principals and Practice of OncologyUpdate Series, J. De Vita, V. T., S. Hellman, and A. Rosenberg, Editors.1988, J. B. Lippincott: Philadelphia, Pa.

There are two classes of drugs that target the TS enzyme: thefluoropyrimidines and the antifolates. The fluoropyrimidines, 5-FU, S-1and capecitabine (Xeloda®), have wide use in the treatment ofgastrointestinal and breast cancers, while the antifolate pemetrexed(Alimta®) is currently used for the treatment of non-small cell lungcancer (NSCLC). Since the discovery of 5-FU over fifty years ago byCharles Heidelberger, the fluoropyrimidines remain one of the mostcommon and effective anticancer cancer drugs used worldwide. Due to thisfact, there is an abundance of clinical experience and insight into themechanism of action of these agents.

The TS inhibitor 5-fluorouracil (5 FU) remains the foundation of manyfirst and second line regimens in the treatment of colon cancer. Singleagent therapies including oxaliplatin, irinotecan, Erbitux and Avastin,demonstrate lowered activity in colon cancer compared to 5-FU. Inaddition to colon cancer, TS-inhibitory agents have demonstratedefficacy in several other solid tumor types. Standard of care nowincorporates 5-FU as the backbone drug in combiniation with oxaliplatinor irinotecan or another agent.

Deoxyuridine triphosphatase (“dUTPase”) is a ubiquitous enzyme that isessential for viability in both prokaryotic and eukaryotic organisms; asthe main regulator of dUTP pools, the expression of dUTPase could haveprofound effects on the utility of chemotherapeutics that inhibitthymidylate biosynthesis. Normally, dUTPase mediates a protective roleby limiting the expansion of dUTP pools and countering the cytotoxiceffect of uracil misincorporation. According to this model, elevatedlevels of dUTPase could prevent TS inhibitor-induced dUTP accumulationand induce drug resistance. It has been shown that dUTPase overexpression results in a significant decrease in dUTP accumulation andincreased resistance to drug treatment when compared to controls.

Chemotherapeutic agents that target de novo thymidylate metabolism arecritical for the treatment of a variety of solid tumors, howeverclinical efficacy is often hindered by drug resistance. Becauseresistance to these agents is a common occurrence, the identificationand exploitation of novel determinants of drug sensitivity within thispathway of proven therapeutic utility is important. As disclosed byLadner et al. in U.S. Patent Publ. No. US 2011/0212467, the dUTPaseenzyme and the uracil-DNA misincorporation pathway can play a drivingrole in mediating cytotoxicity to TS-directed chemotherapies.

For example, nearly half of cancer patients do not benefit from5-FU-based treatment due to intrinsic or acquired drug resistance. Dueto this fact, there is a critical need to overcome the fundamentalchallenge of drug resistance and provide new therapeutic strategies toimprove patient outcome. This disclosure satisfies this need andprovides related advantages as well.

An “effective amount” is an amount sufficient to effect beneficial ordesired results. An effective amount can be administered in one or moreadministrations, applications or dosages. Such delivery is dependent ona number of variables including the time period for which the individualdosage unit is to be used, the bioavailability of the therapeutic agent,the route of administration, etc. It is understood, however, thatspecific dose levels of the therapeutic agents disclosed herein for anyparticular subject depends upon a variety of factors including theactivity of the specific compound employed, bioavailability of thecompound, the route of administration, the age of the animal and itsbody weight, general health, sex, the diet of the animal, the time ofadministration, the rate of excretion, the drug combination, and theseverity of the particular disorder being treated and form ofadministration. In general, one will desire to administer an amount ofthe compound that is effective to achieve a serum level commensuratewith the concentrations found to be effective in vivo. Theseconsiderations, as well as effective formulations and administrationprocedures are well known in the art and are described in standardtextbooks.

“Therapeutically effective amount” of a drug or an agent refers to anamount of the drug or the agent that is an amount sufficient to obtain apharmacological response such as inhibiting dUTPase; or alternatively,is an amount of the drug or agent that, when administered to a patientwith a specified disorder or disease, is sufficient to have the intendedeffect, e.g., treatment, alleviation, amelioration, palliation orelimination of one or more manifestations of the specified disorder ordisease in the patient. A therapeutic effect does not necessarily occurby administration of one dose, and may occur only after administrationof a series of doses. Thus, a therapeutically effective amount may beadministered in one or more administrations.

As used herein, “treating” or “treatment” of a disease in a patientrefers to (1) preventing the symptoms or disease from occurring in ananimal that is predisposed or does not yet display symptoms of thedisease; (2) inhibiting the disease or arresting its development; or (3)ameliorating or causing regression of the disease or the symptoms of thedisease. As understood in the art, “treatment” is an approach forobtaining beneficial or desired results, including clinical results. Forthe purposes of this technology, beneficial or desired results caninclude one or more, but are not limited to, alleviation or ameliorationof one or more symptoms, diminishment of extent of a condition(including a disease), stabilized (i.e., not worsening) state of acondition (including disease), delay or slowing of condition (includingdisease), progression, amelioration or palliation of the condition(including disease), states and remission (whether partial or total),whether detectable or undetectable.

“dUTPase” means any of the following, which are considered to besynonymous, “deoxyuridine triphosphate nucleotidohydrolase”,“deoxyuridine triphosphate pyrophosphatase”, “dUTP nucleotidohydrolase”,“dUTP pyrophosphatase”, and other equivalent nomenclature for thedUTPase enzyme. In one aspect, dUTPase intends DUT-N and DUT-M. In otheraspects, it is DUT-N only, or alternatively, DUT-M only. The amino acidand coding sequences for dUTPase are known in the art and disclosed inU.S. Pat. No. 5,962,246. Methods for expressing and screening forexpression level of the enzyme are disclosed in U.S. Pat. No. 5,962,246and Ladner et al. (US Patent Publ. No. 2011/0212467A1).

“DUT-N” means the nuclear form of dUTPase.

“DUT-M” means the mitochondrial or cytoplasmic form of dUTPase.

“dUTPase-directed therapy” intends therapeutics that target the dUTPasepathway, e.g., in the case of cancer, e.g. TS-directed therapies and thefluoropyrimidines (such as 5-FU), pemetrexed (Alimta®), capecitabine(Xeloda®), S-1 and antifolates (such as methotrexate) and chemicalequivalents thereof. Non-limiting examples include 5-flurouracil (5-FU),TS-directed therapies and 5-FU based adjuvant therapy. Combinationtherapies can include any intervention that alters nucleotide poolsand/or sensitizes the immune cells or viruses to the dUTPase inhibitor,as are well known to the skilled artisan. For rheumatoid arthritis, forexample, the combination can be with an dihydrofolate reductase (DHFR)inhibitor such as methotrexate.

5-fluorouracil (5-FU) belongs to the family of therapy drugs calledpyrimidine based anti-metabolites. It is a pyrimidine analog, which istransformed into different cytotoxic metabolites that are thenincorporated into DNA and RNA thereby inducing cell cycle arrest andapoptosis. Chemical equivalents are pyrimidine analogs which result indisruption of DNA replication. Chemical equivalents inhibit cell cycleprogression at S phase resulting in the disruption of cell cycle andconsequently apoptosis. Equivalents to 5-FU include prodrugs, analogsand derivative thereof such as 5′-deoxy-5-fluorouridine(doxifluoroidine), 1-tetrahydrofuranyl-5-fluorouracil (ftorafur),capecitabine (Xeloda®), S-1 (MBMS-247616, consisting of tegafur and twomodulators, a 5-chloro-2,4-dihydroxypyridine and potassium oxonate),ralititrexed (tomudex), nolatrexed (Thymitaq, AG337), LY231514 andZD9331, as described for example in Papamicheal (1999) The Oncologist4:478-487.

“5-FU based adjuvant therapy” refers to 5-FU alone or alternatively thecombination of 5-FU with other treatments, that include, but are notlimited to radiation, methyl-CCNU, leucovorin, oxaliplatin, irinotecin,mitomycin, cytarabine, levamisole. Specific treatment adjuvant regimensare known in the art as FOLFOX, FOLFOX4, FOLFIRI, MOF (semustine(methyl-CCNU), vincrisine (Oncovin®) and 5-FU). For a review of thesetherapies see Beaven and Goldberg (2006) Oncology 20(5):461-470. Anexample of such is an effective amount of 5-FU and Leucovorin. Otherchemotherapeutics can be added, e.g., oxaliplatin or irinotecan.

Capecitabine is a prodrug of (5-FU) that is converted to its active formby the tumor-specific enzyme PynPase following a pathway of threeenzymatic steps and two intermediary metabolites,5′-deoxy-5-fluorocytidine (5′-DFCR) and 5′-deoxy-5-fluorouridine(5′-DFUR). Capecitabine is marketed by Roche under the trade nameXeloda®.

Leucovorin (Folinic acid) is an adjuvant used in cancer therapy. It isused in synergistic combination with 5-FU to improve efficacy of thechemotherapeutic agent. Without being bound by theory, addition ofLeucovorin is believed to enhance efficacy of 5-FU by inhibitingthymidylate synthase. It has been used as an antidote to protect normalcells from high doses of the anticancer drug methotrexate and toincrease the antitumor effects of fluorouracil (5-FU) andtegafur-uracil. It is also known as citrovorum factor and Wellcovorin.This compound has the chemical designation of L-Glutamic acidN[4[[(2-amino-5-formyl1,4,5,6,7,8hexahydro4oxo6-pteridinyl)methyl]amino]b-enzoyl], calciumsalt (1:1).

“Oxaliplatin” (Eloxatin) is a platinum-based chemotherapy drug in thesame family as cisplatin and carboplatin. It is typically administeredin combination with fluorouracil and leucovorin in a combination knownas FOLFOX for the treatment of colorectal cancer. Compared to cisplatin,the two amine groups are replaced by cyclohexyldiamine for improvedantitumour activity. The chlorine ligands are replaced by the oxalatobidentate derived from oxalic acid in order to improve water solubility.Equivalents to Oxaliplatin are known in the art and include, but are notlimited to cisplatin, carboplatin, aroplatin, lobaplatin, nedaplatin,and JM-216 (see McKeage et al. (1997) J. Clin. Oncol. 201:1232-1237 andin general, Chemotherapy for Gynecological Neoplasm, Curr. Therapy andNovel Approaches, in the Series Basic and Clinical Oncology, Angioli etal. Eds., 2004).

“FOLFOX” is an abbreviation for a type of combination therapy that isused to treat cancer. This therapy includes 5-FU, oxaliplatin andleucovorin. “FOLFIRI” is an abbreviation for a type of combinationtherapy that is used treat cancer and comprises, or alternativelyconsists essentially of, or yet further consists of 5-FU, leucovorin,and irinotecan. Information regarding these treatments are available onthe National Cancer Institute's web site, cancer.gov, last accessed onJan. 16, 2008.

Irinotecan (CPT-11) is sold under the trade name of Camptosar. It is asemi-synthetic analogue of the alkaloid camptothecin, which is activatedby hydrolysis to SN-38 and targets topoisomerase I. Chemical equivalentsare those that inhibit the interaction of topoisomerase I and DNA toform a catalytically active topoisomerase I-DNA complex. Chemicalequivalents inhibit cell cycle progression at G2-M phase resulting inthe disruption of cell proliferation.

The term “adjuvant” therapy refers to administration of a therapy orchemotherapeutic regimen to a patient after removal of a tumor bysurgery. Adjuvant therapy is typically given to minimize or prevent apossible cancer reoccurrence. Alternatively, “neoadjuvant” therapyrefers to administration of therapy or chemotherapeutic regimen beforesurgery, typically in an attempt to shrink the tumor prior to a surgicalprocedure to minimize the extent of tissue removed during the procedure.

The phrase “first line” or “second line” or “third line” etc., refers tothe order of treatment received by a patient. First line therapyregimens are treatments given first, whereas second or third linetherapy are given after the first line therapy or after the second linetherapy, respectively. The National Cancer Institute defines first linetherapy as “the first treatment for a disease or condition. In patientswith cancer, primary treatment can be surgery, chemotherapy, radiationtherapy, or a combination of these therapies. First line therapy is alsoreferred to those skilled in the art as primary therapy and primarytreatment.” See National Cancer Institute website as www.cancer.gov,last visited on May 1, 2008. Typically, a patient is given a subsequentchemotherapy regimen because the patient did not shown a positiveclinical or sub-clinical response to the first line therapy or the firstline therapy has stopped.

As used herein, the term “antifolate” intends a drug or biologic thatimpairs the function of folic acids, e.g., an antimetabolite agent thatinhibits the use of a metabolite, i.e. another chemical that is part ofnormal metabolism. In cancer treatment, antimetabolites interfere withDNA production, thus cell division and growth of the tumor. Non-limitingexamples of these agents are dihydrofolate reductase inhibitors, such asmethotrexate, Aminopterin, and Pemetrexed; thymidylate synthaseinhibitors, such as Raltitrexed or Pemetrexed; purine based, i.e. anadenosine deaminase inhibitor, such as Pentostatin, a thiopurine, suchas Thioguanine and Mercaptopurine, a halogenated/ribonucleotidereductase inhibitor, such as Cladribine, Clofarabine, Fludarabine, or aguanine/guanosine: thiopurine, such as Thioguanine; or Pyrimidine based,i.e. cytosine/cytidine: hypomethylating agent, such as Azacitidine andDecitabine, a DNA polymerase inhibitor, such as Cytarabine, aribonucleotide reductase inhibitor, such as Gemcitabine, or athymine/thymidine: thymidylate synthase inhibitor, such as aFluorouracil (5-FU).

In one aspect, the term “chemical equivalent” means the ability of thechemical to selectively interact with its target protein, DNA, RNA orfragment thereof as measured by the inactivation of the target protein,incorporation of the chemical into the DNA or RNA or other suitablemethods. Chemical equivalents include, but are not limited to, thoseagents with the same or similar biological activity and include, withoutlimitation a pharmaceutically acceptable salt or mixtures thereof thatinteract with and/or inactivate the same target protein, DNA, or RNA asthe reference chemical.

The terms “oligonucleotide” or “polynucleotide” or “portion,” or“segment” thereof refer to a stretch of polynucleotide residues which islong enough to use in PCR or various hybridization procedures toidentify or amplify identical or related parts of mRNA or DNA molecules.The polynucleotide compositions of this invention include RNA, cDNA,genomic DNA, synthetic forms, and mixed polymers, both sense andantisense strands, and may be chemically or biochemically modified ormay contain non-natural or derivatized nucleotide bases, as will bereadily appreciated by those skilled in the art. Such modificationsinclude, for example, labels, methylation, substitution of one or moreof the naturally occurring nucleotides with an analog, internucleotidemodifications such as uncharged linkages (e.g., methyl phosphonates,phosphotriesters, phosphoamidates, carbamates, etc.), charged linkages(e.g., phosphorothioates, phosphorodithioates, etc.), pendent moieties(e.g., polypeptides), intercalators (e.g., acridine, psoralen, etc.),chelators, alkylators, and modified linkages (e.g., alpha anomericnucleic acids, etc.). Also included are synthetic molecules that mimicpolynucleotides in their ability to bind to a designated sequence viahydrogen bonding and other chemical interactions. Such molecules areknown in the art and include, for example, those in which peptidelinkages substitute for phosphate linkages in the backbone of themolecule.

When a genetic marker, e.g., over expression of dUTPase, is used as abasis for selecting a patient for a treatment described herein, thegenetic marker is measured before and/or during treatment, and thevalues obtained are used by a clinician in assessing any of thefollowing: (a) probable or likely suitability of an individual toinitially receive treatment(s); (b) probable or likely unsuitability ofan individual to initially receive treatment(s); (c) responsiveness totreatment; (d) probable or likely suitability of an individual tocontinue to receive treatment(s); (e) probable or likely unsuitabilityof an individual to continue to receive treatment(s); (f) adjustingdosage; (g) predicting likelihood of clinical benefits; or (h) toxicity.As would be well understood by one in the art, measurement of thegenetic marker in a clinical setting is a clear indication that thisparameter was used as a basis for initiating, continuing, adjustingand/or ceasing administration of the treatments described herein.

For example,a fixed dose of a dUTPase directed therapy (e.g., 5-FU or Pemetrexed)can be added to the system and varying amounts of the compound can besubsequently added to system. Alternatively, a fixed dose of a compoundof this invention can be added to the system and varying amounts of thedUTPase directed therapy (e.g., 5-FU or Pemetrexed) compound can besubsequently added to system.

In another aspect, the assay requires contacting a first samplecomprising suitable cells or tissue (“control sample”) with an effectiveamount of a composition of this invention and optionally a dUTPaseinhibitor, and contacting a second sample of the suitable cells ortissue (“test sample”) with the agent to be assayed and optionally adUTPase inhibitor. In one aspect, the cell or tissue over expressdUTPase. The inhibition of growth of the first and second cell samplesare determined. If the inhibition of growth of the second sample issubstantially the same or greater than the first sample, then the agentis a potential drug for therapy. In one aspect, substantially the sameor greater inhibition of growth of the cells is a difference of lessthan about 1%, or alternatively less than about 5% or alternatively lessthan about 10% , or alternatively greater than about 10% , oralternatively greater than about 20%, or alternatively greater thanabout 50%, or alternatively greater than about 90%. The contacting canbe in vitro or in vivo. Means for determining the inhibition of growthof the cells are well known in the art.

In a further aspect, the test agent is contacted with a third sample ofcells or tissue comprising normal counterpart cells or tissue to thecontrol (or alternatively cells that do not over express dUTPase) andtest samples and selecting agents that treat the second sample of cellsor tissue but does not adversely effect the third sample. For thepurpose of the assays described herein, a suitable cell or tissue isdescribed herein such as cancer or other diseases as described herein.Examples of such include, but are not limited to cancer cell or tissueobtained by biopsy, blood, breast cells, colon cells.

Efficacy of the test composition is determined using methods known inthe art which include, but are not limited to cell viability assays orapoptosis evaluation.

In yet a further aspect, the assay requires at least two cell types, thefirst being a suitable control cell.

The assays also are useful to predict whether a subject will be suitablytreated by this invention by delivering a composition to a samplecontaining the cell to be treated and assaying for treatment which willvary with the pathology or for screening for new drugs and combinations.In one aspect, the cell or tissue is obtained from the subject orpatient by biopsy. Applicants provide kits for determining whether apathological cell or a patient will be suitably treated by this therapyby providing at least one composition of this invention and instructionsfor use.

The test cells can be grown in small multi-well plates and is used todetect the biological activity of test compounds. For the purposes ofthis invention, the successful candidate drug will block the growth orkill the pathogen but leave the control cell type unharmed.

Biological Methods A. Drugs, Reagents and Cell Lines

Test compounds are suspended in DMSO at a concentration, e.g., of 100mmol/L, fluorodeoxyuridine (FUdR) that can be obtained from Sigma (StLouis, MO) and maintained in sterile double-distilled water at stockconcentrations of 50 mmol/L.

Recombinant human deoxyuridine nucleotidohydrolase (dUTPase) isexpressed and purified as described in Ladner R D, Carr S A, HuddlestonM J, McNulty D E, Caradonna SJ. J Biol Chem. 1996 Mar 29;271(13):7752-7.All drugs stocks are aliquoted and diluted as appropriate prior to use.The oligonucelotide primer, templates and fluorophore- andquencher-labeled detection probes are synthesized by Integrated DNATechnologies (Coralville, Iowa), subjected to polyacrylamide gelelectrophoresis purification and reconstituted in Omnipur sterilenuclease-free water (EMD Chemicals USA, Gibbstown N.J.) at a stockconcentration of 100 μmol/L. The two non-emissive (dark) quenchingmolecules incorporated into the detection probes include the Iowa blackfluorescein quencher (IBFQ; absorption max 531 nm) and ZEN(non-abbreviation; absorption max 532 nm). The fluorescent labelutilized is 6-FAM (5′-carboxyfluorescein; excitation max.=494 nm,emission max.=520 nm). Probes are further diluted to a working stock of10 μmol/L and aliquoted to avoid repeated freeze/thaw cycles. AmpliTaqGold DNA Polymerase, GeneAmp 10× PCR Buffer 2, MgCl₂ and MicroAmpOptical 96-well Reaction Plates are purchased from Applied Biosystems(Carlsbad, Calif.). dNTPs are purchased individually at stockconcentrations of 100 mmol/L from New England Biolabs atHPLC-certified >99% purity (Ipswich, Mass.).

B. Assay ComponentsI Instrumentation and Real-Time FluorescenceConditions

Reaction mixtures contained primer, probe and template at an equimolarfinal concentration of 0.4 μmol/L. Magnesium chloride (MgCl₂) isincluded at a final concentration of 2 mmol/L. Non-limiting dNTPs areincluded in the reaction mix in excess at a final concentration of 100μmol/L (dUTP/dTTP is excluded). AmpliTaq Gold DNA polymerase is added at0.875U/reaction, 2.5 μl of 10× PCR buffer 2 added and nuclease-freeddH₂O added to a final reaction volume of 25 μl. For dUTP inhibitionanalysis, the volume of ddH₂O is further modified to accommodate anadditional 1 μl of dUTPase (10 ng/μl) and 1 μl of inhibitor or DMSOcontrol. Thermal profiling and fluorescence detection is performed usingthe ‘isothermal’ program on board an Applied Biosystems 7500 Real-TimePCR System. For analysis of dNTPs, the thermal profile consisted of an 8min 37° C. step followed by a 10 min 95° C. step to ‘hot-start’ the Taqpolymerase and a primer extension time of up to 30 min at 60° C.depending on the application. Raw fluorescence spectra for 6-FAM ismeasured using filter A at specified time intervals to follow assayprogression using Sequence Detection Software (SDS Version 1.4, AppliedBiosystems) and exported and analyzed in Microsoft Excel (Microsoft,Redmond Wash.) and Prism (GraphPad Software, La Jolla Calif.).Fluorescence values for blank reactions (limiting dNTP omitted) aresubtracted to give normalized fluorescence units (NFU) to account forbackground fluorescence.

C. MTS Growth Inhibition Assay

The Cell Titer AQueous MTS assay (Promega) is carried out according tothe manufacturers guidelines. IC_(50(72h)) values are calculated fromsigmoidal-dose response curves utilizing Prism (Graphpad, San Diego,Calif.). The combination effect is determined by the combination index(CI) method utilizing Calcusyn software (Biosoft, Ferguson, Mo.).Fraction affected (FA) is calculated from the percent growth inhibition:FA=(100-% growth inhibition)/100. CI values <1, synergism; 1-1.2,additive and >1.2, antagonism.

D. Colony Formation Assay

Colony forming assay showing the ability of colon (SW620, HCT116),non-small cell lung (A549, H460, H1299 and H358) and breast (MCF7)cancer cells to survive and proliferate following transient 24 hourexposure to test compounds, FUdR and combinations are determined.Specifically, cells are seeded at densities between 50 and 100cells/well in 24-well plates. Twenty-four hours later, cells are treatedwith increasing concentrations of a rtest compound, a fixed dose of FUdRand combinations of these. After 24 hours, drug is removed, cells arerinsed and allowed to outgrow for 10-14 days. At the conclusion of theoutgrowth, cells are fixed in 60% ice cold methanol and stained with0.1% crystal violet, scanned and counted. Data is presented aspercentage of untreated controls (mean±SD). Fraction affected andcombination indexes are calculated according to the method of Chou andTalalay where <1 is indicative of a synergistic drug interaction.

E. In vivo Analysis

Xenograft experiments are conducted in male NU/NU nude mice (CharlesRiver, Wilmington, Mass.) that are 6-8 weeks old. Subcutaneous A549xenografts are established and allowed to grow until they reached ˜50mm³ (day 1). Animals are randomized to treatment groups: vehicle,pemetrexed 50 mg/kg, a test compound and combination of pemetrexed plusa test compound (n=5, group). Pemetrexed is administered at 50 mg/kg byintraperitoneal injection every two days. Test compound is administered,e.g., at 75 mg/kg by intraperitoneal injection every two days. Thecombination of pemetrexed and the test compound is administered byintraperitoneal injection, e.g., every two days. Two perpendiculardiameters of tumors are measured every 2 days with a digital caliper bythe same investigator. Tumor volume is calculated according to thefollowing formula: TV (mm³)=(length[mm]×(width[mm]²)/2. Mice areinspected everyday for overall health and bodyweight is measured every 2days as an index of toxicity. All animal protocols are approved by theUSC Institutional Animal Care and Use Committee (IACUC).

dUTPase Inhibition

Test compounds are screened in a fluorescence-based assay. The assayemploys a DNA polymerase-based approach utilizing an oligonucleotidetemplate with 3 distinct regions: a 3′ primer binding region, amid-template dUTP/thymidine triphosphate (TTP) detection region and a 5′6-Flavin adenine mononucleotide (FAM)-labeled probe binding region thatincorporates a black hole quenching moiety. During the reaction, theprobe and primer hybridize to the oligonucleotide template to form thetemplate:primer:probe complex. When Taq polymerase binds to the primerin the TPP complex and dUTP is present, successful extension of thenascent strand occurs and the inherent 5′ to 3′ exonuclease activity ofTaq polymerase cleaves and displaces the 6-FAM-labeled probe in a 5′ to3′ direction, releasing the 6-FAM fluorophore from its proximity to thethree quenchers. This displacement effectively disrupts the Försterresonance energy transfer (FRET) and the resulting fluorescence detectedupon excitation is directly proportional to the amount of the dUTPavailable in the assay for incorporation. Conversely, when the dUTP isunavailable, exhausted, or degraded by dUTPase and is no longeravailable for incorporation, Taq polymerase stalls and extension delayand/or chain termination of the nascent strand occurs. In this instance,probe hydrolysis/degradation does not occur and the probe remains darkas fluorescence remains quenched via FRET. Since fluorescence isdirectly proportional to the concentration of dUTP, the assay is easilymodified to measure dUTP and the effects of inhibitors on dUTPhydrolysis by the enzyme dUTPase. The template BHQ-DT6 (Black HoleQuencher—Detection Template 6) for detecting up to 60 pmols of dUTP isincluded for this application of the assay along with 50 pmols of dUTPand 5 ng of recombinant dUTPase. The reaction is incubated at 37° C. for8 mins and terminated by a 10 min incubation at 95° C. to simultaneouslyinactivate dUTPase and activate the hot-start Taq polymerase. Thefluorescence generated during the detection step is directlyproportional to the concentration of dUTP remaining after the 8 minincubation. The concentration of dUTP at reaction termination andtherefore inhibition of dUTPase in the presence and absence ofinhibitors and appropriate dimethyl sulfoxide (DMSO) controls can bedetermined.

Test compounds are evaluated for their antitumor activity in colorectalcancer cells using the MTS growth inhibition assay. HCT116 and SW620cells are exposed to increasing concentrations of each agent for 72hours and growth inhibition is directly compared to vehicle-treatedcontrols. The NSCLC cell lines A549 and H1299 are exposed to increasingconcentrations of each agent for 72 hours and growth inhibition isdirectly compared to vehicle-treated controls.

Growth Inhibition

MTS growth inhibition assays are performed to evaluate the effectivenessof the tyest compounds alone and in combination with thefluoropyrimidine thymidylate synthase (TS) inhibitor 5-fluorouracil(5-FU) at inhibiting the growth of colorectal (HCT116 and SW620) cellline models. Increasing concentrations of 5-FU between 0 and 100 μmol/Ldemonstrated dose-dependent increases in growth inhibition in both thecolorectal cancer cell lines evaluated. Simultaneous treatment withincreasing concentrations of 5-FU and a test compound at fixedconcentrations of 25 μmol/L is determined.

Reducing Cancer Cell Viability

Colony forming assays are performed to evaluate the effectiveness oftest compounds alone and in combination with the fluoropyrimidinethymidylate synthase (TS) inhibitor fluorodeoxyuridine (FUdR) atreducing cancer cell viability in colorectal (HCT116), breast (MCF-7)and non-small cell lung (H1299, A549, H358 and H460) cell line models.Increasing concentrations of FUdR between 0.5 and 2.5 μmol/Ldemonstrated dose-dependent decreases in colonies formed in all celllines evaluated.
